You don't need to clean fuling village from inhabitants. Eat three best foods for stamina, take one stamina bottle and run naked into the village. Steal flax or barley, then run away. Then you have two options: first is to dir from enemies in relatively safe space to recover tombstone; or jump through throwaway portal to main base.

Also it's good to establish plains farm on a small island where is no spawns (or just turn them off with crafting tables)
